What GEMÜ does

GEMÜ (legal entity: Gebr. Müller Apparatebau GmbH & Co. KG) is a privately held, family-owned German industrial technology company founded in 1964 and headquartered in Kupferzell, Germany, with CEO and Managing Partner Gert Müller. The company designs, manufactures, and sells valves, measurement and control systems, fittings, and customized fluid-handling solutions for process industries including pharmaceutical and biotech, semiconductors, food and beverage, water technology, hydrogen and Power-to-X, chemical engineering, mining, and energy and environmental technology. Its technology portfolio centers on proprietary diaphragm and diaphragm-seat valve designs (GEMÜ PD technology), the patented CleanStar double-diaphragm measurement isolation, SUMONDO single-use valve architecture, and multi-port block valve systems that consolidate multiple functions into single units to reduce leak paths and documentation burden.

The company operates a five-pillar product architecture: (1) valve technology (diaphragm, seat, butterfly, ball, control, pinch, single-use valves), (2) measurement and control technology (position/process controllers, flow meters, pressure and temperature sensors), (3) connection technology (fittings and hoses for high-purity media), (4) customized product solutions including multi-port block valves and PUPSIT-compliant configurations, and (5) digital solutions comprising the ValveSizer sizing tool, digital engineering simulation, the GEMÜ mobile app, CONEXO RFID/QR/NFC asset lifecycle management, and Digital Product Passport software. Manufacturing is conducted under ISO 13485 and ISO Class 8 cleanroom conditions, with components compliant with EU MDR, FDA, USP, EP, and EU GMP Annex 1 requirements.

GEMÜ generates revenue primarily through direct hardware sales of engineered valves and measurement/control systems, supplemented by engineering services for customized solutions and an emerging subscription/recurring stream from digital tools. Distribution is executed through more than 50 wholly-owned subsidiaries and authorized sales partners providing field-sales, application engineering, and after-sales service across the Americas, Europe, Asia/Pacific, the Middle East, and Africa. Pricing is quote-based for customized enterprise accounts and standard catalog-based through an online shop for registered business customers. The company has no public listing, no disclosed external funding, and no public revenue disclosure.
